The argument that can be made is that I was hoping my membership dues would be for legal defense and lobbyists versus pandering to the demographic that already supports them.

On the other side of that people like to see their money being spent. You dont see the money spent on lobbiest and such but you do see a car going 200 mph with NRA plastered on it. Having millons staring at the NRA message for hours is priceless.
Anothr team has Sandy hook awareness or something like that on their car for the same race. This shows that the fight over the second amendment is affecting ever one.
